Summary:2.1 In the known processes for the oligomerisation of olefins having 2 to 8 carbon atoms, the nickel-containing catalyst has only a short service life, so that the catalytic oligomerisation processes have hitherto been uneconomical on a large industrial scale. It is intended that the novel process is distinguished by a good service life of the catalyst. 2.2 Before oligomerisation, the hydrocarbon feed mixture is passed through a molecular sieve having a pore diameter of greater than 4 ANGSTROM ngströms to 15 ANGSTROM ngströms. 2.3 Preparation of olefin oligomers having 4 to 16 carbon atoms.
